I can’t remember where I saw it, I want to say it was somewhere on this website, but Star Wars has always had an issue with time compression (the main example I saw was that the entirety of TESB was supposed to take over months, but you never get that idea from the movie itself).

Here’s an idea I literally had just now. How about after Luke rescues Grogu and takes him, cut the goodbye scene short, cut to Boba Fett taking over Jabba’s operations, then cut to Mando at Luke’s planet, asking Ahsoka to give Grogu the beskar chain mail. It makes a minor plothole of how did Mando get on and off Luke’s planet, but it would solve a major pacing issue, both in transitioning from Mando 2 material to TBoBF material, as well as all the waiting Mando & the audience have to do to even meet Ahsoka & drop off the gift. Just make the transition from show material as quick/engaging as possible and hope people don’t complain.
